It actually happened for Barcelona btw, look at their performance after losing some key players in their starting line-up which has clearly declined apart from the victory against several La Liga clubs who can be said to be quite far below them and the defeat against Inter in the Meeting first this clearly shows that they are not doing well. I personally saw this condition and maybe it will be at odds for Madrid later.
This is El classico and that says it all. This match has its own separate meaning in itself, regardless of the state of Real Madrid and Barcelona, what place they occupy in the championship standings, how they perform in the Champions League. Of course, this also has its own significance, but it is not necessarily decisive, because a team that has some failures may try to take a kind of revenge for this and vice versa. It is also worth considering that this is not the final part of the championship and a defeat in this match will not put an end to hopes for the championship title, so the excessive responsibility of this plan should not put pressure on the players. I believe that Real Madrid will have some advantage, but only because Real Madrid will be the host of the match. And so, Barcelona also has a good chance of success.
